John Matthew Holt, Waratek CTO, explains how Waratek Cloud VM for Java transforms the JVM with key Cloud characteristics including genuine multitenancy, granular elasticity, instant scalability, realtime metering and prioritization of resources by application, to futureproof your Java investment in the age of Cloud computing.

3. The Problem with Java!
• Java is 15 years old, predates multitenant cloud computing
• JavaEE app servers were designed to host multiple webapps,
but rarely do in practice because there's no isolation between
webapps
• Today's JavaSE/JavaEE apps are deployed as "one app per
app-server per JVM", which leads to "app-server sprawl”
• Hosting one webapp per JVM means provisioning fixed cpu/
memory quotas which can't elastically fluctuate on demand.

4. The Problem with Java!
• Hosting one webapp per fixed cpu/memory quota means
there is unused cpu/memory capacity being paid for: this is a
waste
• Today's JavaSE/JavaEE apps are perfectly suited to a
multitenant "pay exactly what you consume" model were there
a multitenant JVM
• A multitenant JVM would be able to charge computing power
like a utility: gigahertz-hours for cpu, gigabyte-hours for
memory

5. Virtualizing the Java Platform!
• The Waratek Cloud VM introduces a feature called Java
Virtualization Containers (JVC)
• A JVC is a metacircular VM within the JVM which shares the
host JVM environment (heap, classes, JIT) with other JVCs
• A JVC is extremely lightweight: < 1 MB overhead per JVC
JVC 1! JVC 2! JVC 3!

6. Fine-grained resource control!
• A single VM can host thousands of JVCs:
a JVC can be any size (from 1MB up to many GBs)
• Every aspect of JVC execution is isolated:
cpu priority, memory limits, bandwidth, etc
• Every aspect of JVC use is metered:
cpu use in Hz, memory/IO use in Bytes
• JVCs provide computing power like electricity kW-h:
cpu consumed in GHz-h, memory consumed in GB-h

7. Waratek Cloud VM delivers Java-as-a-Service!
• Run JavaSE/JavaEE platform software as a multitenant cloud
service without code change:
binary compatible with existing apps and platforms
• Every .war/.ear/.jar app gets its own JVC
.war app! .ear app! .jar app!
Tomcat / JBoss / GlassFish / Other !

8. Extensible Java Virtualization!
• JVC framework is fully extensible and customizable:
enhanced JVCs can be created by anyone using Waratek
APIs
• Special-purpose JVCs already in dev or planning:
Servlet JVCs for Tomcat, EAR JVCs for JBoss, Scala JVC,
Clojure JVC, et al
• Waratek is adding a range of premium JVC features:
legacy JVCs, live snapshot, live migration, JVC mirroring
for disaster-recovery, etc.
